LAWN-TRIMLTER.

.Application filed July 28, 1915. Serial No. 42,315.

I '0 all whom it concern Be it known that we, Jonu C SCHULTZ and (insurers T. AMMoN, citizens of the United States, residing at lVooster, in the county of .lVaync-and State of Ohio, have invented certain'new and useful Improve-- ments in Lawn-Trimmers, of which the following is a specification.

Our invention relates to improvements in lawn trimmers or edgors, the primary ob ject of the invention being to provide a generally improved tool or implement of this class of exceedingly simple, cheap, and ellicient construction admirably adapted to be forced along the edge of a foot walk, curl)- iug, side walk, or the like, whereby to simultaneously cut and remove the overlapping turf and form a groove or channel along the edges thereof.

A further object is the provision of an improved cutting and grooving member having a forwardly projecting share sect-ion the latter being provided. with a rearwardly and downwardly inclined lawn or turf cutting edge adapted to initially cut and return the turf to the grooving portion of the tool, this tool or implement diii'ering from the ordinary form in that the. latter has the point of its grooving portion or section extending aheadof the side cutting edges so that the furrow or groove is initially out or in other words before the turf is removed or cut thus leaving a rough ragged edge.

A'still further object is to improve the general construction, arrangement, and adjustment of the parts to meet the varying demands of actual service.

With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement, andcombination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying' drawings, and particularly pointed Referring to the drawings, forming a part out in the appended claim.

of thisv specification, Figure 1, is aside ole trating its manner of application and use. Fig. 2, a, top plan view of the same. Fig. 3, an enlarged detail side elevation of the outer or shareside of the same. Fig. 4, a vie'w of the inner or reverse side of some. Fig. "5, an enlarged top plan view or the same.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The improved lawn trimmer comprises a handle 1, adapted to be supported and carried at its lower end by means of a supporting wheel 2, the latter being adapted to travel upon and along the marginal edge of the adjacent walk or curbing 3, as indicated in F igs. l and 2 of the drawings, and carrying with it the improved cutting and grooving member or compound blade 4, constructod and mounted as hereinafter -de scribed.

Thc improved cutting and grooving memher 4, is secured to one side of the handle 1, through the medium of adjusting screw bolts 5, secured in a. supporting plate 6, the latter being secured to the base or head portion of the handle through the medium of suitable attaching bolts 6. bolts 5, in the supporting plate 6, through suitable slots 4', in the base or attaohing portion of the cutting and grooving member to permit the latter to be adjusted to meet the varying demands of actual service, such as increasing or decreasing the The adjusting Patented May o, 1916.

(iii

depth and width of the cut-away or channel portion formed by the improved tool.

The cutting and grooving member has an. outwardly inclined forwardly projecting share or lawn cutting section or portion said section or. portion 4", having a rear- Wardly and downwardly inclined cutting" edge 4;, terminating in a channel shaped base section 4", it being. the object of the share or lawn cutting-section 4", and particu'larly its draw cutting edge 4, to cut land vtrim the lawn and sod'in advance of the roovin section 4 as well as to cut and remove the forward portion and return it to the channel shaped base section of the implemcnt -so that'ghe cut-away or trimmed portions of the lawn and sod will be returned intothe grooved or channeled part 7, as indicated at 7", in Fig. 2 of the drawings.

The vertically extendi section 4*, preferably has its cutting Edge 4, extending downwardly and rearwardly toward the one section 4", said verticallv extending or walk'side'section being adapted to pass along and beguidedby the marginal edge of the walk or curbing 3, (as thecase may be). to

form the vertically extending edge of the channel or groove 7, at the adjacent or contiguous side thereof. The supporting wheel ting section well extended forwardly so that the rearwardly and downwardly inclined cutting edge 1 extends at an acute angle and will have an initial draw cutting contact atthe surface of the lawnor ground and then finally out out the bottom of the groove or furrow leaving the sod or cut-away portion rest undisturbed in the furrow or groove thus leaving a clean cut smooth edge as illustrated most clearly in Fig. 2 of the drawings. It will also be observed. that the lawn cutting and vertically ext-ending sections 4 and 4", have their cutting edges 4- and i", respectively, undercut for the purpose of permitting the implement to give the initial draw-cutting contact to the surface of the lawn or ground as hereinhefore explained and shown most clearly in Fig. 1 of the drawings.

From the foregoing description, taken in connection with the accompanying draw iugs, the operation and advantages of our nal plane of said handle, and a cutting and grooving member adjustably mounted on the side of said supporting plate opposite said supporting wheel and consisting of walk and lawn cutting sections each having undercut rearwardly and downwardly inclined cutting edges terminating in a horizontally extending channel shaped base section'materially below the planes of said supporting plate and wheel, said lawn cutting section including a tapered forwardly projectin snare portion having an acute angled draw cutting edge in advance of the cutting edge of said walk cutting section.

In testimony whereof we have aflixed our signatures in the presence of two witnesses.
